Sound insulation according to DIN 4109

The DIN 4109 sets requirements for the achievable minimum sound protection primarily in housing but also for schools, hospitals, accommodation and office buildings and explicitly regulates the requirements in the form of the following sound insulation criteria:

  • Air and impact sound from foreign living and recreation rooms or stairwells
  • Outside noise
  • Noises of water installations from external lounges or stairwells
  • Noises of building services (including heating and ventilation systems in your own living area)
  • User noises due to structure-borne sound transmission from external lounges or stairwells
  • Air and impact sound in your own living and lounge area
  • Noises of water installations in your own living and lounge area
  • A / V ratio (reverberation times) in stairwells

These are based on the protection goals of health protection, confidentiality in normal speech and protection against unreasonable harassment. This is stated in paragraph 1

"This standard specifies requirements for sound insulation with the aim of protecting people in lounges from unreasonable disturbances caused by sound transmission."

This means that the design planner must be prepared for all the requirements that are placed on a building - among others. for soundproofing - ultimately finding a solution that is reasonably and economically feasible and can withstand a legal review.

Soundproofing systems

Who doesn't know that, there are rooms where you can no longer understand your own word, but you can hear every single word from neighboring tables. Airborne noise and noise are not only exhausting, violate privacy and paralyze performance and concentration in the workplace, they also have a harmful effect on our health.

For example, larger restaurants, open-plan offices, conference rooms, lecture halls, canteens and generally high, open rooms are particularly prone to unpleasant noise development due to their architecture. With an acoustic concept and sound-absorbing systems for the ceiling, floor and wall, rooms can be positively influenced and the noise level can be drastically reduced.

A wide variety of systems, which can be individually adapted to the respective situation, are available to builders. Our services include:

  • Creation of an individual acoustic concept
  • Attaching acoustic ceilings and wall panels with:
    • Diamond plates as cladding in high-quality drywall systems with increased noise protection requirements, fire protection requirements, requirements for robustness and in moderately damp rooms
    • Knob or pyramid foam
    • Plasterboard in perforated or slotted form
    • Sound-absorbing panels with HiTec insulation fleece or mineral wool

We also assemble special soundproof booths for our customers, which are used both in the private sector, for example as a rehearsal room for amateur musicians, and in the semi-professional sector as a recording studio or for noisy work.
